Description

Food processor and machine head of food processor

Technical Field

The invention relates to the technical field of food processing, in particular to a food processor and a machine head of the food processor.

Background

The soybean milk maker is mainly classified into two types from the crushing technology, one type is the soybean milk maker with a grinder, and the other type is the non-net soybean milk maker (namely, the soybean milk maker is disturbed by the disturbing flow ribs on the barrel wall). The two soymilk makers have advantages and disadvantages, some advantages of the soymilk maker with the turbulence cover are just the disadvantages of the soymilk maker without a net, and some disadvantages of the soymilk maker with the turbulence cover are just the advantages of the soymilk maker without a net. For example, the soymilk grinder with the turbulence cover has the advantages of low grinding noise, high grinding efficiency and the like, but has poor grinding effect, large-particle food materials exist in the prepared soymilk, and the soymilk grinder is inconvenient to clean; the non-net soymilk machine has good crushing effect, but has large noise and low crushing efficiency. The two soymilk makers have contradiction which is difficult to reconcile, and some advantages of the two soymilk makers cannot be integrated. In addition, when the rotating speed of the crushing knife is high, the motor is high in load and easy to damage.

Disclosure of Invention

The present application is based on the discovery and recognition by the inventors of the following facts and problems:

for a soymilk maker with a turbulence cover, slurry can be attached to the turbulence cover and a gap between the turbulence cover and a machine head. In the correlation technique, vortex cover and aircraft nose can not split or the split difficulty, take the aircraft nose of vortex cover not only weight can increase, glue the edible material that the vortex was covered moreover, especially the edible material that is located between vortex cover and the aircraft nose is difficult and inconvenient to be clear away usually, great increase the washing degree of difficulty of soybean milk machine, lead to the use frequency reduction of user to the soybean milk machine.

The reason that the soymilk grinder with the turbulence cover has poor crushing effect is as follows: the vortex scope of its vortex cover is concentrated on smashing sword and vortex cover part, because receives the influence of vortex cover, the bucket wall position far away from the vortex cover, and the liquid velocity of flow is lower, can't in time wash the food of deposiing, leads to some food along the collection time overlength, and the adhesion is near the bucket wall, can't collide and smashed with smashing the cutter, finally leads to can have the food of complete granule in the food of having made, influences the preparation quality of food. In addition, when the food material is in a large block shape, the food material cannot or is not easy to enter from the feed inlet of the turbulence cover, so that the food cannot be crushed.

The reason why the mesh-free soybean milk machine has good crushing effect is that the mesh-free soybean milk machine has no influence of the turbulence cover, the flow velocity of the whole liquid in the barrel body is higher, even if the flow velocity of the liquid near the barrel wall far away from the crushing knife is also higher, food materials can be quickly washed, the food materials are prevented from being deposited and adhered to the barrel bottom, and therefore, the prepared food does not have unbreakable granular food.

In the related art, for example, in the soymilk makers disclosed in patents CN202664139U, CN201403473Y, and CN203493420U, etc., the spoiler cover is fixedly disposed on the machine head, six degrees of freedom (movement in the X direction, movement in the Y direction, movement in the Z direction, rotation around the X axis, rotation around the Y axis, and rotation around the Z axis) are all limited, the spoiler cover cannot move and rotate during operation, the relative positions of the spoiler cover and the crushing knife are fixed, and the crushing effect of the soymilk maker is poor due to the presence of the spoiler cover. Based on the above documents, the inventor of the present application finds and recognizes that the poor grinding effect of the soymilk machine is a common problem of the soymilk machine with the turbulence cover, and few soymilk machines can simultaneously take the grinding effect, the grinding efficiency, the working noise and the like into consideration.

In view of this, the present application provides a machine head of a food processor, the machine head has a grinder, and the grinder can adjust the position along the axial direction of the machine head, so that the relative position between the grinding member and the grinder can be changed, and further, the grinding characteristics of a grinding system composed of the grinding member and the grinder are changed. Therefore, the user can adjust the setting height of grinder according to the characteristics of different foods, reach better crushing effect, the noise is lower simultaneously, smash efficiently, has both solved the defect of taking vortex cover soybean milk machine and no net soybean milk machine in the past, possesses both advantages again, has solved difficult problem in the trade to the implementation scheme is simple, and is reliable, and manufacturability is good.

In addition, in the related art, the turbulence cover of the soymilk machine with the turbulence cover only has one working state, and in the running process of the soymilk machine, the turbulence cover is not always fixed or always rotates, so that the working mode can not be changed according to the real-time load condition, and the motor can not be protected. The grinder of the soymilk machine can automatically switch between rotation and rest along with the size of the motor load, so that the soymilk machine is not easy to generate foam, the motor load can be reduced, and the motor is well protected from being burnt out.

According to the head 100 of the food processor of the embodiment of the invention, the grinder 30 can have a plurality of mounting positions in the axial direction of the head body 10, so that the grinding characteristics of the grinding system formed by the grinding piece 40 and the grinder 30 can be changed, and a user can adjust the grinding characteristics of the head 100 according to the characteristics of the food materials, so as to achieve good grinding and grinding effects on the food materials.

According to some embodiments of the present invention, the handpiece 100 may further include a rotating sleeve 60, the rotating sleeve 60 may be pivotably fitted on the handpiece body 10, and the grinder 30 may be connected to the rotating sleeve 60 so that the grinder 30 is adjustable in position in the axial direction of the rotating sleeve 60 as the rotating sleeve 60 pivots with respect to the handpiece body 10. Therefore, the grinder 30 can be switched among a plurality of mounting positions in the axial direction of the rotary sleeve 60, so that the position of the grinder 30 in the axial direction of the head body 10 can be changed, the adjustment is convenient, and the rotation performance of the grinder 30 is good.

To achieve the position adjustment of the grinder 30 in the axial direction of the rotating sleeve 60, optionally, a plurality of positioning portions may be provided on the rotating sleeve 60, and the plurality of positioning portions may be provided at intervals in the axial direction of the rotating sleeve 60. The grinder 30 may be provided with a positioning fitting adapted to be fitted with any one of the positioning portions and switchable between the plurality of positioning portions so that the grinder 30 is adjustable in position in the axial direction of the rotary sleeve 60. Therefore, the grinder 30 can be accurately installed and positioned on the rotating sleeve 60 and the position adjustment operation is convenient through the matching of the positioning part and the positioning fitting piece.

It will be appreciated that the detent and the locating engagement element may be of various configurations. Alternatively, in some embodiments of the present invention, the positioning portion may be formed as a positioning groove 110, the positioning fitting member may be formed as a resilient member 50, one end of the resilient member 50 may be connected to the grinder 30 and the other end of the resilient member 50 is adapted to resiliently abut against any one positioning groove 110 and may be switched among a plurality of positioning grooves 110. Therefore, the grinder 30 can be easily adjusted in the axial position, the adjustment operation is convenient, the head 100 is not damaged, the manufacture is convenient, and the cost is relatively low.

The following describes a machine head 100 of a food processor according to an embodiment of the present invention in detail with reference to various embodiments shown in the drawings, wherein the machine head 100 is suitable for being mounted on a barrel of the food processor. Referring to fig. 1 to 11, a machine head 100 of a food processor according to an embodiment of the present invention may include: a handpiece body 10, a motor 20, a grinder 30 and a grinding member 40.

The motor 20 may be provided in the head body 10, and the grinder 30 is connected to the head body 10. The grinding member 40 is disposed in the grinding chamber 301 of the grinder 30 and is rotated by the motor 20. In other words, the motor 20 may be disposed in the handpiece body 10, the grinder 30 may be disposed on the handpiece body 10, the grinding chamber 301 may be defined in the grinder 30, and the grinding element 40 may extend into the grinding chamber 301. The motor 20 may be coupled to the shredder member 40 to drive the shredder member 40 in rotation. Alternatively, the pulverizing member 40 may be a pulverizing blade, and the motor 20 may be directly connected to the pulverizing member 40 or indirectly connected thereto.

For example, in some embodiments of the present invention, the reducing elements 40 are coupled to the motor shaft of the motor 20, and the motor 20 is operated such that the motor shaft rotates the reducing elements 40. For another example, in other embodiments of the present invention, the handpiece 100 is provided with a rotating shaft, the pulverizing member 40 is provided on the rotating shaft, the rotating shaft is connected to a motor shaft, and when the motor 20 is operated, the motor shaft rotates the rotating shaft, and the pulverizing member 40 rotates along with the rotating shaft.

An anti-overflow bar 14 can be arranged on the handpiece body 10, and the anti-overflow bar 14 can be connected with a control circuit 13 in the handpiece body 10. When the machine head 100 is arranged on the barrel body, the anti-overflow rod 14 can extend into the barrel body, so that the food processor can have an anti-overflow function, the working performance of the food processor is good, and the use safety is improved. The structure and operation of spill guard 14 will be known to those skilled in the art and will not be described in detail herein.

As shown in fig. 1 to 4, a positioning groove 110 may be formed on the head body 10, the positioning groove 110 may extend in a ring shape along a circumferential direction of the head body 10, and a plurality of elastic assemblies 50 may be disposed on the grinder 30, and the plurality of elastic assemblies 50 may be spaced apart from each other along the circumferential direction of the grinder 30. Of course, the structure of the handpiece 100 is not limited thereto, and the installation positions of the positioning groove 110 and the elastic assembly 50 may be interchanged, that is, the positioning groove 110 may be provided on the grinder 30 and extend in a ring shape along the circumferential direction of the grinder 30, the elastic assembly 50 may be provided on the handpiece body 10, and the elastic assemblies 50 may be provided at intervals along the circumferential direction of the handpiece body 10. That is, one of the grinder 30 and the handpiece body 10 is provided with a positioning groove 110 extending annularly along the circumferential direction thereof, and the other of the grinder 30 and the handpiece body 10 is provided with a plurality of elastic assemblies 50 spaced apart along the circumferential direction thereof.

When the positioning groove 110 is provided on the outer circumferential surface of the head body 10 and the plurality of elastic members 50 are respectively provided on the grinder 30, not only is it more convenient to manufacture, but also the elastic members 50 can be separated from the head body 10 along with the grinder 30, it is more labor-saving to clean the elastic members 50, and only the grinder 30 needs to be replaced or the grinder 30 needs to be replaced when the elastic members 50 are damaged, and maintenance cost is low.

Each elastic component 50 is elastically stopped in the positioning groove 110 to elastically connect the grinder 30 to the handpiece body 10. That is to say, each elastic component 50 has a connecting portion connected to the grinder 30 or the handpiece body 10 and a stopping portion extending into and stopping in the positioning groove 110, the handpiece body 10 and the grinder 30 can be elastically connected by the cooperation of the elastic component 50 and the positioning groove 110, a certain elastic stopping force can be formed between the grinder 30 and the handpiece body 10, when the elastic component 50 is subjected to a force greater than the elastic stopping force, the stopping portion of the elastic component 50 can be moved out of the positioning groove 110, so that the elastic component 50 is disengaged from the positioning groove 110, the elastic connection between the grinder 30 and the handpiece body 10 can be released, and the grinder 30 can be detached from the handpiece body 10.

When actual split operation, the user can exert certain split power to grinder 30, and at this moment, elastic component 50 also can receive the split strength effect, and when split power was greater than elasticity thrust, elastic component 50 can break away from the cooperation with constant head tank 110 to make the elastic constraint between grinder 30 and the aircraft nose body 10 remove, grinder 30 can move about for aircraft nose body 10, the separation with aircraft nose body 10 is realized.

According to the machine head 100 of the food processor, the grinder 30 can be elastically connected with the machine head body 10 by arranging the plurality of elastic assemblies 50 and the positioning grooves 110, the grinder 30 can be separated from the machine head body 10, so that the grinder 30 can be independently taken out for cleaning, food materials adhered to the grinder 30 and food materials loaded in a gap between the grinder 30 and the machine head body 10 can be completely removed, the cleaning difficulty of a user is greatly reduced, the cleaning operation is more convenient, and the cleaning is cleaner. Wherein, a plurality of elastic component 50 and constant head tank 110 end simultaneously and support and make mill 30 and aircraft nose body 10 can have a plurality of elastic connection points in circumference, connect comparatively for firmly, the equilibrium is better, and a plurality of elastic connection points can independently carry out dismouting, easy dismounting respectively. The handpiece 100 is easy to manufacture, has a reliable structure and is relatively low in cost.

In addition, when the handpiece 100 is operated, due to the existence of the elastic stopping force between the elastic assembly 50 and the positioning groove 110, a friction force can be formed between the grinder 30 and the handpiece body 10 in the circumferential direction, namely, a damping force can exist between the grinder 30 and the handpiece body, and the damping force can limit the grinder 30 to pivot relative to the handpiece body 10. When the load of the motor 20 is small, the rotating speed of the food material in the barrel body is relatively low, the impact force of the food material on the grinder 30 is small, the damping force applied to the grinder 30 is relatively large, and the grinder 30 does not rotate relative to the machine head body 10; when the load of the motor 20 is large, the rotating speed of the motor 20 is high, the rotating speed of the food material in the barrel body is also relatively high, the impact force of the food material on the grinder 30 is large, and when the impact force is relatively large, the grinder 30 can overcome the damping force and rotate relative to the handpiece body 10. At this time, the grinder 30 may disperse, crush and grind the food materials, may share the load of the motor 20, and may play a role in protecting the motor 20.

That is, there is a damping force between the grinder 30 and the handpiece body 10, and when the damping force is greater than the acting force applied to the grinder 30 in the circumferential direction of the grinder 30, the damping force acts, the grinder 30 remains stationary with respect to the handpiece body 10, and the abutment position of each elastic assembly 50 in the positioning groove 110 remains stationary; when the damping force is less than or equal to the acting force applied to the grinder 30 in the circumferential direction of the grinder 30, the grinder 30 can pivot relative to the handpiece body 10 around the axis of the handpiece body 10, and the plurality of elastic assemblies 50 simultaneously stop against the positioning groove 110 to move, so that the grinder 30 is still limited in the axial direction of the handpiece body 10, and the grinder 30 can axially rotate without axial translation.

In the related art, the turbulence cover of the soymilk machine with the turbulence cover only has one working state, and in the running process of the soymilk machine, the turbulence cover is not always fixed or always rotates, so that the working mode can not be changed according to the real-time load condition, and the motor can not be protected. And the grinder 30 of the aircraft nose 100 of the food processor of this application can be changed into along with the size of the load of motor 20 is automatic to rotate or not rotate, makes the soybean milk machine be difficult for producing the foam and the load of motor 20 can reduce, and fine protection motor 20 is not burnt out.

Since the grinder 30 is connected to the head body 10 by the plurality of elastic members 50, the grinder 30 is not completely in contact with the head body 10 in the circumferential direction, and therefore, when the grinder 30 pivots with respect to the head body 10, a sliding contact area between the grinder 30 and the head body 10 is relatively small, a sliding friction force is small, the grinder 30 can smoothly pivot and the head body 10 is also not easily worn, and the working performance of the head 100 is good.

As shown in fig. 2 to 4, the positioning groove 110 may include a plurality of positioning grooves 110, and the plurality of positioning grooves 110 may be provided at intervals in the axial direction of the head body 10. The plurality of elastic members 50 may elastically abut against the same positioning groove 110 and be switchable between the plurality of positioning grooves 110. That is to say, the outer peripheral surface of the handpiece body 10 has a plurality of positioning grooves 110 at different heights, and the plurality of elastic assemblies 50 can be stopped at the same positioning groove 110, so that the grinder 30 can be elastically connected to the handpiece body 10, and the plurality of elastic assemblies 50 can not only be disengaged from the positioning grooves 110, but also be disengaged from the positioning grooves 110 and then be engaged with another positioning groove 110 at a different height, at this time, the connection position between the handpiece body 10 and the grinder 30 changes, that is, the position of the grinder 30 in the axial direction of the handpiece body 10 can change.

When a plurality of positioning grooves 110 are provided in the axial direction of the head body 10, the grinder 30 may have a plurality of mounting positions in the axial direction of the head body 10, the grinder 30 may be switched between the plurality of mounting positions, and the relative positions between the grinder 30 and the pulverizing member 40 at different positions may not be different. That is, when the grinder 30 is positionally shifted in the axial direction of the head body 10, the position of the grinding member 40 in the grinding chamber 301 may be changed. Thereby, the grinding characteristics of the grinding system consisting of the grating member 40 and the grinder 30 can be varied. The user can adjust the setting height of the grinder 30 according to the requirements of different foods, select the corresponding optimal position, achieve better grinding effect, and make the food material obtain the optimal making effect.

According to the machine head 100 of the food processor, the axial installation position of the grinder 30 can be set according to the characteristics of different food materials, so that the machine head 100 can have better grinding and grinding effects on different food materials, the machine head 100 can keep the advantages of lower noise, high grinding efficiency and the like, and can also have the advantage of good grinding effect of a mesh-free soybean milk machine, the defects of the conventional soybean milk machine with a turbulence cover and the conventional soybean milk machine without a mesh cover are overcome, the advantages of the machine head 100 and the conventional soybean milk machine without a turbulence cover are also achieved, the industrial problem is solved, and the machine head 100 is simple in implementation scheme, reliable and strong in manufacturability.

As shown in fig. 2, according to some embodiments of the present invention, the distance H between the upper surface of the grinding element 40 and the top wall surface of the grinding chamber 301 (i.e. the lower surface of the top wall of the grinder 30) in the axial direction of the handpiece body 10 may be in the range of: h is more than or equal to 5mm and less than or equal to 100 mm. Therefore, the machine head 100 can have a good crushing effect on most food materials. When the H value is larger, the turbulent flow effect of the crushed water-material mixed liquid is poor, the flow velocity of the water surface of the mixed liquid and the liquid close to the barrel wall is relatively increased, the food material can be prevented from being adhered to the barrel wall due to the increased flow velocity, the problem that food particles cannot be crushed due to the adhesion of the food particles to the barrel wall is solved, and the effect is remarkable for preparing food with particles or food with larger initial particles; when the H value is smaller, the water-material mixed liquid has better turbulent flow effect, and the crushing effect is more excellent for some harder foods.

For example, in some embodiments of the present invention, H may take on a value of 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, and the like.

It can be understood that the head body 10 is not limited to be provided with the positioning groove 110, and positioning portions of other structures can be provided, and the grinder 30 is not limited to be provided with the elastic component 50, and positioning matching pieces of other structures can be provided, as long as the positioning matching pieces can be detachably matched with each other by the positioning portions, and the damping force can be formed between the grinder 30 and the head body 10.

The grinder 30 may be provided with a plurality of positioning engagement pieces adapted to be engaged with any one of the positioning portions at the same time and switchable between the plurality of positioning portions, so that the grinder 30 is switched in position along the axial direction of the handpiece body 10. When the positioning portion is not formed as the positioning groove 110, but formed as another structure, another structure may be provided on the flange of the outer cover 122 or the flange of the grinder 30. This is understood and readily accomplished by those of ordinary skill in the art and will not be described in detail herein.

Referring to fig. 1 to 5, a mounting hole 302 and a plurality of mounting grooves 303 may be provided on a top wall of the grinder 30, the plurality of mounting grooves 303 respectively communicating with the mounting hole 302. The mounting opening 302 and the mounting groove 303 penetrate the top wall of the grinder 30 in the thickness direction of the top wall of the grinder 30. A plurality of mounting slots 303 may be spaced apart along the circumference of the grinder 30. The handpiece body 10 can be inserted into the mounting opening 302, and a part of each elastic component 50 is arranged in the corresponding mounting groove 303. From this, in the circumference of mill 30, mill 30 and aircraft nose body 10 can realize elastic fit in many places, and the connection between mill 30 and the aircraft nose body 10 is more firm, and mill 30 installs more steadily balanced, has guaranteed the stationarity and the reliability of aircraft nose 100 subassembly operation.

Wherein the maximum radial dimension of the portion of the handpiece body 10 lower than the top wall of the grinder 30 may be less than or equal to the radial dimension of the mounting opening 302. That is, the handpiece body 10 may pass through the mounting port 302 from above downward, or the grinder 30 may be fitted on the handpiece body 10 from below the handpiece body 10, and the maximum radial dimension of the portion of the handpiece body 10 located below the top wall of the grinder 30 may be smaller than or equal to the radial dimension of the mounting port 302. When the grinder 30 and the handpiece body 10 need to be detached, a user can apply a downward acting force to the grinder 30, and the elastic assembly 50 can be pulled out from the positioning groove 110 after being stressed, so that the grinder 30 can be taken out downward. After the grinder 30 is cleaned, the grinder 30 can be assembled from the lower part of the handpiece body 10, and the elastic assembly 50 can be matched with the positioning groove 110 by applying upward acting force to the elastic assembly 50, so that the grinder 30 is convenient to assemble and disassemble.

In some specific examples of the present invention, the downward force F1 applied when detaching the grinder 30 may have a value range of: f1 is not less than 0.5N and not more than 100N, and accordingly, the upward acting force F2 applied when the grinder 30 is installed can take the value range as follows: f2 is more than or equal to 0.5N and less than or equal to 100N.

As shown in fig. 2, 4 and 5, the radial dimension of the grinding member 40 may be greater than the radial dimension of the mounting port 302, and the top wall of the grinder 30 may be provided with an avoiding hole 304 communicated with the mounting port 302, and the avoiding hole 304 may avoid the grinding member 40 when the grinder 30 is disassembled and assembled, and the grinding member 40 does not need to be disassembled and assembled when the grinder 30 and the grinding member 40 are separated, so that the grinder 30 is convenient to disassemble and assemble. It will be appreciated that the projected area of the avoiding hole 304 in the axial direction of the handpiece body 10 should be greater than or equal to the projected area of the pulverizing element 40 in the axial direction of the handpiece body 10, so as to facilitate the grinder 30 to pass through the pulverizing element 40 during the mounting and dismounting without being interfered by the pulverizing element 40. Of course, the reducing member 40 can be made detachable or the reducing member 40 can be deformed to avoid the grinder 30 when the grinder 30 does not have the avoiding hole 304.

As shown in fig. 5, the mounting grooves 303 may be formed as rectangular grooves opening toward the center of the mounting opening 302, the number of the mounting grooves 303 may be four, the avoidance holes 304 may also be formed as four, and the four mounting grooves 303 and the four mounting openings 302 may be spaced apart in the circumferential direction of the grinder 30. Therefore, the whole structure of the grinder 30 is balanced, the grinder 30 is good in balance and good in operational reliability, and the assembly is more flexible. The avoiding hole 304 can also be used as a feeding hole or a discharging hole of the grinder 30, so that a special feeding hole and a special discharging hole are not required to be arranged on the grinder 30, and the structure of the grinder 30 is simpler.

Here, it should be noted that the number of the mounting grooves 303 may also be three, five, six, or the like, and accordingly, the number of the elastic components 50 may also be three, five, six, or the like, and may be flexibly set. The number of the elastic assemblies 50 is preferably more than three, so as to ensure that the grinder 30 is reliably connected with the handpiece body 10 and the balance is good.

It is understood that the structure of the elastic assembly 50 may be variously formed, and alternatively, each elastic assembly 50 may include an elastic member 51 and a latch 52, respectively. The elastic member 51 may be provided in the mounting groove 303, the elastic member 51 may extend toward the center of the mounting opening 302, and one end of the elastic member 51 may be connected to the grinder 30. The latch 52 may be connected to the other end of the elastic member 51, and the latch 52 is adapted to be stopped in the positioning groove 110 by the elastic force of the elastic member 51.

Therefore, when acting force is applied to the grinder 30, the elastic element 51 can deform, and the locking tongue 52 can move into or out of the positioning groove 110, so that the elastic component 50 is matched with or separated from the positioning groove 110, and the matching effect is good. Alternatively, the elastic member 51 may be formed as a spring that can be expanded and contracted in the axial direction of the mounting groove 303 to easily move the latch tongue 52 into and out of the mounting groove 303.

Referring to fig. 6 to 8, in other embodiments of the present invention, the elastic assembly 50 may further include a limiting cylinder 53, the limiting cylinder 53 may be connected to the grinder 30, and the limiting cylinder 53 may be disposed in the mounting groove 303. The limiting cylinder 53 may define therein a limiting groove 531 having an end opened toward the center of the mounting opening 302, in other words, the limiting cylinder 53 may define therein the limiting groove 531, and an end of the limiting groove 531 facing the center of the mounting opening 302 may be opened. The elastic member 51 may be disposed in the limiting groove 531, one end of the elastic member 51 may be connected to the bottom wall of the limiting groove 531, specifically, the elastic member 51 has a free end and a fixed end, the fixed end may be connected to the bottom wall of the limiting groove 531, and the free end may be provided with a locking tongue 52. The latch tongue 52 may extend into the stopper groove 531 and be movable in the axial direction of the stopper groove 531. Here, the axial direction of the limiting groove 531 may be the radial direction of the grinder 30, and at least a portion of the latch 52 may be disposed in the limiting groove 531 and may be moved along the axial direction of the limiting groove 531 as the elastic member 51 is deformed.

From this, spacing section of thick bamboo 53 not only can play the effect of protection elastic component 51, but also can play the guide effect to the removal of spring bolt 52 and the deformation of elastic component 51, and elastic component 50 is easy to assemble and not fragile, and the direction of deformation is invariable, and it is steady and reliable to warp.

The plural locking tongues 52 can simultaneously rest in the same positioning groove 110 by the elastic force of the respective elastic members 51, and the plural locking tongues 52 can be switched between the plural positioning grooves 110 spaced apart in the axial direction of the head 100. Specifically, when the position of the grinder 30 needs to be adjusted, an acting force can be applied to the grinder 30, the elastic member 51 can deform in the axial direction of the limiting groove 531 under the acting force, and drives the locking tongue 52 to move out of the positioning groove 110, when the locking tongues 52 all move out of the positioning groove 110, the axial restraint applied to the grinder 30 is released, and the grinder 30 has a degree of freedom to move upward or downward in the axial direction of the handpiece body 10. When the grinder 30 moves to the next installation position, the plurality of locking tongues 52 correspond to the positioning grooves 110, and can automatically extend into and abut against the positioning grooves 110 under the action of the elastic force of the respective elastic members 51, at this time, the plurality of elastic members 50 all abut against the same positioning groove 110, the plurality of elastic members 50 are switched between different positioning grooves 110, the grinder 30 moves in the axial direction of the head body 10, the adjustment operation is convenient, and the head 100 is convenient to manufacture.

As shown in fig. 3 and 6, according to some embodiments of the present invention, the latch tongue 52 may include a connecting portion and a stopping portion. The connection portion may be provided in the stopper groove 531, and the connection portion may be connected to the elastic member 51. The stopping portion may be connected to the connecting portion, and the stopping portion may extend out of the limiting groove 531 and stop in the positioning groove 110. The stopping portion may have a stopping surface adapted to stop against an inner wall surface of the positioning groove 110, the stopping surface may include a curved surface 521 and an annular inclined surface 522, and the annular inclined surface 522 may be connected to an outer circumferential edge of the curved surface 521. The annular ramp 522 may extend obliquely outward and toward the center of the mounting opening 302 in an axial direction along the limiting groove 531. The positioning groove 110 may be formed as a curved groove, that is, the inner wall surface of the positioning groove 110 may be formed as a curved surface 521, for example, as shown in fig. 3 and 6, the positioning groove 110 may be formed as a curved groove having a semicircular section.

When the latch 52 abuts against the positioning slot 110, the curved surface 521 may abut against an inner wall surface of the positioning slot 110, and the annular inclined surface 522 may abut against an outer peripheral edge of the positioning slot 110. That is, the latch tongue 52 may make a surface-type contact with a small area with the inner wall surface of the positioning groove 110, and at the same time, may make a similar point-type contact with the outer circumferential edge of the positioning groove 110. In the process of moving the locking tongue 52 into or out of the positioning groove 110, the annular inclined surface 522 can be stopped against the outer edge of the positioning groove 110 to move, the annular inclined surface 522 has a guiding effect on the moving-in and moving-out of the locking tongue 52, meanwhile, the contact area between the locking tongue 52 and the positioning groove 110 is smaller, not only can the inner wall surface of the positioning groove 110 not be damaged by the locking tongue 52, but also the friction resistance received when the locking tongue 52 moves is smaller, so that the grinder 30 is labor-saving when the position is switched, meanwhile, the friction received when the grinder 30 overcomes the damping force to pivot is smaller, the grinder 30 pivots more smoothly, and the machine head body 10 is not easy to wear.

The latch 52 may be an integrally formed member that not only facilitates manufacturing and assembly, but also secures the overall structural integrity of the spring assembly 50. Alternatively, the latch tongue 52 may be made of the same material as the outer cover 122, for example, made of stainless steel.

Referring to fig. 9 to 11, in other embodiments of the present invention, the elastic assembly 50 may further include an elastic strip 54, a portion of the elastic strip 54 may be disposed in the mounting groove 303, one end of the elastic strip 54 may be connected to the grinder 30, and the other end of the elastic strip 54 may elastically abut against the positioning groove 110 when the elastic assembly 50 is engaged with the positioning groove 110. Thus, the elastic member 50 is not only easier to manufacture, but also to engage and disengage the elastic member 50 with and from the positioning groove 110.

Alternatively, one end of the elastic piece may be connected to the top wall of the grinder 30 and extend into the grinding chamber 301, and the other end of the elastic strip 54 may be formed in a bent type, as shown in fig. 9 to 11. Therefore, the other end of the elastic strip 54 not only can be provided with a matching part matched in the positioning groove 110, but also can be provided with a protruding part protruding out of the positioning groove 110, when the grinder 30 is disassembled and assembled, the elastic strip 54 can be easily moved into or out of the positioning groove 110 by pulling the protruding part at the other end of the elastic strip 54, and the disassembling and assembling operation is convenient. The elastic strip 54 is easy to manufacture, uses less material and has lower cost.

Of course, the structure of the elastic component 50 is not limited thereto, and other structures are also possible, for example, the elastic strip 54 may be replaced by a torsion spring, an elastic sheet, or the like. One end of the torsion spring or the elastic sheet can be connected to the grinder 30, and the other end of the elastic strip 54, the torsion spring or the elastic sheet is suitable for being elastically stopped in the positioning groove 110. Thereby, the elastic connection of the grinder 30 and the handpiece body 10 can also be realized. The structure of the spring plate or torsion spring is understood and readily implemented by those of ordinary skill in the art and will not be described in detail herein.

In the embodiment shown in fig. 1 to 11, the grinder 30 of the handpiece 100 is cooperatively connected to the handpiece body 10, and the grinder 30 is not rotated in a case where the load of the motor 20 is small and is rotated in a case where the load of the motor 20 is large, so that the motor 20 can be protected. In the embodiment shown in fig. 12 to 22, the handpiece 100 includes a rotating sleeve 60 in addition to the grinder 30 and the handpiece body 10, the grinder 30 is connected to the rotating sleeve 60, and the rotating sleeve 60 is connected to the handpiece body 10. In this configuration, the grinder 30 can pivot with the rotating sleeve 60 even when the motor 20 is under a low load, so that the handpiece 100 can have a good grinding and grinding efficiency.

The motor 20 may be provided in the head body 10. The grinding member 40 is disposed in the grinding chamber 301 of the grinder 30 and is rotated by the motor 20. The rotating sleeve 60 is pivotally sleeved on the handpiece body 10. That is, the rotating sleeve 60 is fitted over the handpiece body 10 and is pivotable with respect to the handpiece body 10. The rotating sleeve 60 is provided with a positioning groove 110, the positioning groove 110 extends along the circumferential direction of the rotating sleeve 60 to form a ring, the grinder 30 is provided with a plurality of elastic assemblies 50, and the elastic assemblies 50 are arranged at intervals along the circumferential direction of the grinder 30.

Each elastic assembly 50 elastically abuts against the positioning groove 110 to elastically connect the grinder 30 to the rotating sleeve 60.

Therefore, the elastic connection between the grinder 30 and the rotating sleeve 60 can be realized through the matching of the elastic assembly 50 and the positioning groove 110, and a user can overcome the elastic force of the elastic assembly 50 to switch the elastic assembly 50 and the positioning groove 110 between matching and disengaging, so that the grinder 30 can be separated from the rotating sleeve 60. The grinder 30 can be independently taken out for cleaning, thereby greatly reducing the cleaning difficulty of users. Wherein, the elastic components 50 stop against the positioning groove 110 simultaneously, so that the grinder 30 and the rotary sleeve 60 can have a plurality of elastic connection points in the circumferential direction, the connection is firm, and the elastic connection points can be respectively and independently assembled and disassembled, and the disassembly and the assembly are convenient. The handpiece 100 is easy to manufacture and relatively low in cost.

Can set up the position of grinder 30 on rotatory sleeve 60 according to the difference of eating the material in the ladle body, adjust conveniently, grinder 30 can rotate along with rotatory sleeve 60, rotates steadily and smoothly.

It will be appreciated that, since the rotating sleeve 60 can pivot the grinder 30 relative to the handpiece body 10, in the embodiment shown in fig. 12 to 22, each annular positioning groove 110 can be replaced by a plurality of single grooves that are not in communication. Specifically, a plurality of single grooves can be arranged on the grinder 30 or the rotating sleeve 60, the plurality of single grooves can be arranged along the circumferential direction of the grinder 30 or the rotating sleeve 60 at intervals, the plurality of single grooves respectively correspond to the plurality of elastic assemblies 50 one by one, and each elastic assembly 50 can elastically stop against the corresponding single groove, so that the grinder 30 and the rotating sleeve 60 are provided with a plurality of elastic connection points in the circumferential direction, the reliable and stable elastic connection between the grinder 30 and the rotating sleeve 60 is realized, the grinder 30 is more stably and evenly installed, and the running stability and the reliability of the assembly of the handpiece 100 are ensured.

Referring to fig. 12 to 16, the positioning groove 110 may be provided on the outer circumferential surface of the rotating sleeve 60, and a plurality of elastic members 50 may be provided on the grinder 30, respectively.
